If you're looking for a real G-body with serious V8 power, this 1985 Chevrolet Monte Carlo SS delivers. Under the hood is a 400 Small Block Chevy V8 making approximately 400 horsepower, fed by a Holley 650 CFM 4-barrel carburetor. It's backed by a Stage 1 200-4R overdrive transmission with a 2500-stall torque converter and performance upgrades, making it equally at home on the street or highway.

This Monte Carlo has excellent low-end torque and pulls hard throughout the RPM range. The built Stage 1 200-4R shifts firm and positive thanks to the performance internals and shift kit, while the overdrive makes it comfortable to cruise at highway speeds. The upgraded cooling system, ignition, and drivetrain components make it a dependable, turn-key street machine.
Like any 40-year-old classic, it isn't perfect. It has:
A small ding on one fender
The headliner needs to be replaced
A small spot in the trunk that needs repaired
No heat or A/C
These are cosmetic issues and do not affect how the car runs or drives. The drivetrain is where the investment has been made, making this an excellent opportunity to own a strong-running G-body without paying to build one yourself.
Monte Carlo SS values continue to climb, and cars with quality performance upgrades are becoming harder to find. If you're looking for a classic street machine with a healthy 400 SBC, a professionally upgraded overdrive transmission, and thousands invested in performance parts, this car is worth a serious look.
Clean title. No trades.
